How many times have you begun to study for an exam and after 30 minutes get distracted and move on to doing something else, and at the end you are left with no other choice but to stay up all night studying for that final at 8:00 am? Well, Study Ball is here to solve the problem.

The Study Ball gadget is a prison-style ball and chain that you can program to keep track of how much time you spend studying. Once you’ve selected the desired duration, you chain the ball to your ankle and the manacle won’t come off until the schedule study time is up.

A red LED indicator displays the “Study Time Left“ and keeps you informed as to how much longer you’ve got to keep studying. The ball and chain are made of highly durable steel and weighs a total of 9.5 kg / 20.95 pounds, which makes it difficult to move while wearing it.

For safety, the Study Ball cannot be programmed for more than 4 hours. Minors should not use it unless supervised by an adult. It comes with a safety key for emergency deactivation. Link - via coolest-gadgets

$101.69 seems pretty pricey for a gag. Incidentally, the bit about carrying it around? The chain is only 16.5 inches long, which means it pretty much stays on the ground. And ~20 pounds is plenty if you are having to drag the thing by your ankle.

Then, I guess I'm the only one who followed the link. I think it's pretty funny that it's in the site's "gifts for boyfriends" section. :)
